uiGridConstants.filter not in the list

[nallagondaa]

In the angualr JS UIGrid how can I filter values that are not present in the given list, say I have a column with "released" and "amended" as values, I don't want the rows with these 2 values, we have conditions like uiGridConstants.filter.EXACT etc (http://ui-grid.info/docs/#!/api/ui.grid.service:uiGridConstants#properties_filter)

I have tried all of them, but there nothing like NOT_IN filter I want filter out some values from Grid, I am not using any select options here just filter them out is the requirement
